Tension-resistant impact-resistant cable material for large power and preparation method thereof

Abstract

The invention discloses a tension-resistant impact-resistant cable material for large power. The tension-resistant impact-resistant cable material is prepared from 3-4 parts by weight of nanometer barium sulfate, 1-2 parts by weight of a promoter ZDC, 3-5 parts by weight of an acrylate copolymer elastomer, 4-6 parts by weight of a silane cross-linking agent, 20-30 parts by weight of broken waste and old cable, 35-55 parts by weight of silicone rubber, 3-5 parts by weight of sulphur, 2-4 parts by weight of a maleic anhydride-grafted polyolefin elastomer, 4-5 parts by weight of triallyl isocyanurate, 3-4 parts by weight of silicone oil, 3-4 parts by weight of diphenyl methane-4,4'-diisocyanate, 4-6 parts by weight of polyurethane, 2-4 parts by weight of potassium nitrate, 3-5 parts by weight of benzoyl peroxide and 8-12 parts by weight of a filler. The tension-resistant impact-resistant cable material has excellent tensile strength and tearing strength. Through use of polyurethane, impact resistance, hydrolysis resistance and oil resistance of the product are improved. The tension-resistant impact-resistant cable material is a novel cable material with a high economic value.

Description

technical field [0001] The invention relates to the technical field of a cable material, in particular to a high-power tensile and impact-resistant cable material and a preparation method thereof. Background technique [0002] With the development of my country's economy and the rapid development of the communication industry, more and more high-power equipment is used, which puts forward higher requirements for the performance of cables. The withstand power of the cable is linearly related to the difference between the maximum temperature of the inner conductor and the ambient temperature, and the maximum working temperature of the inner conductor is limited by the cable insulation material. The long-term working temperature of the cable insulation material is the maximum allowable working temperature of the inner conductor, but at present Most of the cable materials on the market do not have excellent high temperature resistance and cannot meet the needs of current high-po...
